Popis: A steady-state model for the coupling of a proton exchange membrane fuel cell and an air source heat pump (PEMFC–ASHP) is established in this paper. The influence of reaction pressure and relative humidity on the polarization curve and operating characteristics of PEMFC, as well as the influence of ambient temperature and compressor speed on the system performance are investigated. The results show that the increase of reaction pressure and relative humidity is conducive to the improvement of fuel cell output voltage and efficiency, and the influence of reactant gas relative humidity is more obvious. As the increase of ambient temperature and compressor speed, the heat pump efficiency and system efficiency decrease. The research results can provide theoretical guidance for the design and operation of the PEMFC–ASHP system.
